DEVIPRIYA V VENKATESAN

Abstract


Aberrant ICA is a rare abnormal condition that can be associated with life threatening ear bleed. It was first           reported by Max in 1899 and the incidence is very rare. It occurs usually due to erosion of medial wall of middle ear, congenital anomalies or dilatation of ICA in the petrous part of

temporal bone due to an aneurysm. Misdiagnosis of patients with aberrant ICA leads to unnecessary explorative surgical procedures and or localized treatment which carries risk of massive haemorrhage or even hemiplegia and death.
